Several parallel paths are being pursued in the further development of grinding processes. On the one hand, since higher material removal rates are to be realized, machines of greater rigidity with more efficient drives ...

A quantitative model considering signal attenuation and tool flank wear is proposed to describe the influence of machining process parameters on the level of acoustic emission (AE) generation. The AE sensitivities to width ...

Since Electric Discharge Machining (EDM) has been made available to industry, substantial improvements have been achieved from the point of view of overall machining efficiency throughout the last decades. Even by the fact ...

Axisymmetric forging of powdered-metal preforms was analyzed by the finite element method neglecting the effect of temperature on deformation. A remeshing program based on the area-weighted-average technique was developed ...

Rao and Chaturvedi [18] had presented an analysis to consider the effect of thickness on the forming limit diagrams through a correction in the MK model taking into consideration the influence of the triaxial stress state ...

In this paper, the solutions to the stochastic differential equations, which mathematically represent the machine tool work-piece system in BTA deep hole machining are presented. The solutions to the parametric stochastic ...

A three dimensional model of the BTA deep-hole machining system is presented by modelling each of the components separately and later combining to represent the total system. A model for the interaction between the workpiece ...

As America refocuses its attention on the factory, design and manufacturing engineers must work together closely to design the appropriate products, and matching production process in a team effort. By building off the ...

This paper presents a general method for the design, analysis and optimization of mechanical press linkages. In order to use the method, the linkage type must be identified, and geometrically proportioned to approximately ...

A computer model is developed to simulate the electro-magnetic and the heat-transfer behaviors of the taper heating process. The computer-aided tool can provide the necessary information for design and operation of induction ...

The finite element formulation for deformation of porous materials including compressibility of the material and the effect of temperature was developed and applied to the problem of plane-strain compression of sintered ...

No manufacturing process is complete until the exterior finish is applied to the manufactured part. For exterior service, an environmentally resistant coating is required. For the worst case marine environment, a new ...

In the manufacturing of heavy forgings, one of the most important aspects of the process is the consolidation of internal voids which result from the ingotmaking process. To insure a good quality finished product, these ...

Experimental work on impingement casting process of Pb-Zn, Pb-Zn-Sn and Al-Pb systems was carried out. Rapid mixing of immiscible liquid metals was achieved in an arrow-shaped mixing chamber due to vigorous turbulence. The ...

Theoretical analysis for turbulent mixing in an isotropic turbulent field was carried out. Depending on the material properties and flow field, either viscous shear force or dynamic pressure force breaks-up the globules. ...

Great advances have been made in laser technology in recent years. Near net shape manufacturing technology, on the other hand, has attracted attention to the products of expensive and difficult-to-machine materials. It is ...

The physio-chemical characteristics of aluminium are cause of considerable difficulties in the welding of this material. Even if the technological level reached with traditional technologies for some types of alloy makes ...
